Dragonfly is a high-performance, multi-model in-memory data store designed to serve as a drop-in replacement for existing database infrastructures. By utilizing a multi-threaded, shared-nothing architecture and a fiber-based concurrency model, it maximizes CPU utilization and minimizes latency for read and write operations. The system supports a wide range of data structures, including strings, hashes, lists, sets, sorted sets, and JSON documents, while maintaining full compatibility with standard industry wire protocols and client libraries. What distinguishes Dragonfly is its focus on effic

Vitess is a database clustering system for horizontal scaling of MySQL. It functions as a middleware layer that abstracts complex sharding and physical topology, allowing applications to interact with a distributed database environment through a unified interface. By intercepting and routing SQL queries across multiple shards, it enables large-scale data management while maintaining the appearance of a single database instance. The platform distinguishes itself through its ability to perform online schema migrations and distributed transaction coordination without requiring application downti

This project is a database extension that enables horizontal scaling and distributed data partitioning across multiple PostgreSQL nodes. It functions as a middleware solution that distributes large database tables across a cluster to increase total storage capacity and improve write performance for growing datasets. The system employs hash-based partitioning to distribute table records across physical nodes and uses a central metadata catalog to track shard locations. It provides transparent query routing, which directs standard SQL commands from a coordinator node to the appropriate worker n
